Unresectable Metastatic Solid Pseudopapillary Pancreatic Neoplasm Treated With Liver Transplantation.

We present a 49-year-old woman requiring living donor liver transplantation after liver metastasis from a pancreatic solid pseudopapillary tumor. After identifying a pancreatic mass and liver lesions, she underwent extensive surgical resection. Pathology revealed a solid pseudopapillary neoplasm of the head and body of the pancreas, extending into the peripancreatic soft tissues and confirmed to have spread to the liver.

Imaging in Upper Tract Urothelial Carcinoma: A Review.

Medical imaging is a critical tool in the detection, staging, and treatment planning of upper urinary tract urothelial carcinoma (UTUC). This article reviews the strengths and weaknesses of the different imaging techniques and modalities available clinically. This includes multidetector computed tomography (CT), multiparametric magnetic resonance imaging (MRI), ultrasound (US), and positron emission tomography (PET) for the detection, staging, and management of UTUC.

Pulmonary Perfusion Scan Mimicking Hepatobiliary Scintigraphy in a Patient With an Uncommon Manifestation of Granulomatosis With Polyangiitis.

A 36-year-old man with known granulomatosis with polyangiitis underwent quantitative ventilation-perfusion pulmonary scintigraphy as part of an initial evaluation for lung transplant candidacy. Radiotracer uptake on the perfusion study has the appearance of the hepatic silhouette, drawing initial concern that there may have been a misadministration of Tc with a hepatobiliary agent. Comparison CT reveals extensive cystic bronchiectasis, parenchymal destruction, and volume loss involving the entire left lung and basal portions of the right lung, with the residual portions of functional lung parenchyma conforming to a shape similar to the liver.
